Mistakes

 The history of nuclear energy and its various fields of application has had accidents, more or less serious, all over the world. It is time to review, so as not to forget, 10 mistakes that have left some painful lessons:

1. Kyshtym Disaster (1957): The Kyshtym disaster was a nuclear accident that occurred on September 29, 1957, in the Soviet Union. It resulted in a severe release of radioactive contamination into the surrounding area. The incident was caused by a failure in the cooling system of a nuclear waste tank, which led to an explosion and fire. The disaster was kept secret by the Soviet authorities for many years, and it is still considered one of the worst nuclear accidents in history.
2. Windscale Nuclear Fire (1957): The Windscale nuclear fire occurred on October 10, 1957, at the Windscale nuclear plant in the UK. The fire was caused by a graphite core that caught fire and released a significant amount of radioactive material into the environment. The incident was kept secret by the British government for many years and is considered one of the worst nuclear accidents in the UK's history.
3. SL-1 Accident (1961): The SL-1 accident occurred on January 3, 1961, at the National Reactor Testing Station in Idaho, USA. The accident resulted in the deaths of three people and caused widespread radioactive contamination. The cause of the accident was a control rod that was removed too far, causing a nuclear reaction to occur.
4. Lilo Radiation Accident (1968): The Lilo radiation accident occurred on May 22, 1968, at the Lilo laboratory in Georgia, USA. The accident was caused by the mishandling of radioactive material and resulted in the exposure of several workers to high levels of radiation. The incident led to the death of one worker and the contamination of the laboratory and surrounding areas. This accident had a significant impact on radiation safety regulations in the United States.
5. Lucens Reactor Accident (1969): The Lucens reactor accident occurred on January 21, 1969, in Switzerland. The accident was caused by a loss of coolant and resulted in the release of radioactive material. The incident led to the closure of the reactor and the evacuation of nearby areas.
6. Three Mile Island Accident (1979): The Three Mile Island accident occurred on March 28, 1979, at the Three Mile Island nuclear plant in Pennsylvania, USA. The accident was caused by a partial meltdown of the reactor core and resulted in the release of radioactive gases. Although no deaths or injuries were reported, the incident had a significant impact on the public's perception of nuclear energy.
7. Chernobyl Disaster (1986): The Chernobyl disaster occurred on April 26, 1986, in Ukraine. It is considered the worst nuclear accident in history. The accident was caused by a combination of human error and design flaws in the reactor. The explosion and subsequent fire released large amounts of radioactive material into the environment, causing widespread contamination and many deaths.
8. Goiânia Accident (1987): The Goiânia accident occurred on September 13, 1987, in Brazil. The accident was caused by the theft of a source of radioactive material from an abandoned hospital. The radioactive material was then sold to scrap dealers, leading to widespread contamination and four deaths.
9. Tokaimura Accident (1999): The Tokaimura accident occurred on September 30, 1999, at a nuclear fuel processing plant in Japan. The accident was caused by the improper handling of uranium and resulted in the exposure of three workers to high levels of radiation. Two of the workers later died from their injuries.
10. Sellafield Fire (1957): The Sellafield fire occurred on October 10, 1957, at the Sellafield nuclear reprocessing plant in the UK. The fire released a significant amount of radioactive material into the environment. The incident was kept secret by the British government for many years.
